Translation guide
Describes having two identical alleles for a gene. In Japanese, this is a technical term primarily used in genetics and biology.
The standard scientific meaning: an organism is homozygous for a trait when it has two copies of the same allele.
The most common technical term, used as a noun or with の to modify nouns.
この個体はその遺伝子についてホモ接合です。
This individual is homozygous for that gene.
ホモ接合のマウスは病気を発症した。
The homozygous mice developed the disease.
A synonym using kanji, often seen in formal written contexts.
同型接合体は両親から同じ対立遺伝子を受け継いでいる。
A homozygote inherits the same allele from both parents.
Kanji version of homozygote; less common than ホモ接合体.
同型接合体の頻度を計算する。
Calculate the frequency of homozygotes.
Heterozygous is ヘテロ接合 (hetero setsugō) or 異型接合 (ikei setsugō). The pair ホモ/ヘテロ is very common in Japanese scientific writing.
この遺伝子座はホモ接合かヘテロ接合か？
Is this locus homozygous or heterozygous?
These terms are highly technical. In everyday conversation, you might explain the concept instead: 「両親から同じタイプの遺伝子を受け継いでいる」(inheriting the same type of gene from both parents).
Specifically refers to a homozygous organism or cell (homozygote).
ホモ接合体とヘテロ接合体を比較した。
We compared homozygotes and heterozygotes.
